Abstract

A mobile device includes a metal back cover and a feeding antenna element. The metal back cover has a slot. The slot has an open end and a closed end. The feeding antenna element is coupled to a signal source, and extends across the slot. An antenna structure is formed by the metal back cover, the slot, and the feeding antenna element.

Claims

1. A mobile device, comprising:

a metal back cover, having a slot, wherein the slot has an open end and a closed end; and

a feeding antenna element, coupled to a signal source, and extending across the slot;

wherein an antenna structure is formed by the metal back cover, the slot, and the feeding antenna element.

2. The mobile device as claimed in claim 1, wherein the slot substantially has a straight-line shape or an inverted L-shape.

3. The mobile device as claimed in claim 1, wherein the feeding antenna element substantially has a rectangular shape or a straight-line shape.

4. The mobile device as claimed in claim 1, wherein the feeding antenna element substantially has an inverted J-shape or a T-shape or an L-shape.

5. The mobile device as claimed in claim 1, wherein the slot comprises a first portion and a second portion, the first portion is adjacent to the open end, the second portion is adjacent to the closed end, and the feeding antenna element extends across the second portion.

6. The mobile device as claimed in claim 1, wherein the antenna structure further comprises:

a parasitic element, coupled to the metal back cover, and extending across the slot.

7. The mobile device as claimed in claim 6, wherein the parasitic element substantially has a straight-line shape.

8. The mobile device as claimed in claim 1, wherein the antenna structure is excited to generate a first frequency band and a second frequency band, the first frequency band is from about 2400 MHz to about 2500 MHz, and the second frequency band is from about 5150 MHz to about 5850 MHz.

9. The mobile device as claimed in claim 8, wherein the metal back cover and the slot are excited to generate the first frequency band, and the feeding antenna element is excited to generate the second frequency band.

10. The mobile device as claimed in claim 1, wherein the antenna structure is a first antenna structure, and the mobile device further comprises:

a second antenna structure, wherein the second antenna structure is substantially a mirror image of the first antenna structure.
